Description

La présente invention concerne un aérateur, comme décrit dans la revendication 1, pour introduire de l'air dans l'habitacle d'un véhicule, notamment d'une automobile, comprenant un corps creux pourvu d'un orifice d'entrée relié à une source d'air et d'un orifice de sortie débouchant dans l'habitacle, ainsi qu'un diffuseur de parfum intégré au corps creux et comportant une source de parfum.The present invention relates to an aerator, as described in claim 1, for introducing air into the passenger compartment of a vehicle, particularly an automobile, comprising a hollow body provided with an inlet port connected to a a source of air and an outlet opening into the passenger compartment, and a perfume diffuser integrated in the hollow body and having a source of perfume.

Certaines personnes incommodées par les odeurs régnant parfois dans les habitacles des véhicules installent un diffuseur de parfum au voisinage immédiat de l'un des aérateurs de ces derniers.Some people, who are bothered by the odors sometimes found in vehicle interiors, install a perfume diffuser in the immediate vicinity of one of their air vents.

Ces diffuseurs sont toutefois difficiles à installer car l'aménagement intérieur des véhicules actuels n'est pas conçu pour les recevoir.These diffusers are however difficult to install because the interior of the current vehicles is not designed to receive them.

Ils sont en outre relativement peu efficaces du fait qu'ils peuvent rarement être disposés sur la trajectoire de l'air sortant des aérateurs.They are also relatively inefficient because they can rarely be arranged on the path of the air leaving the aerators.

WO 02/066274 décrit un aérateur selon le préambule de la revendication 1.WO 02/066274 discloses an aerator according to the preamble of claim 1.

FR-A-2 821 022 décrit un aérateur permettant de parfumer l'air introduit dans l'habitacle d'un véhicule, cet aérateur comprenant un corps creux délimitant un conduit dans lequel l'air circule pour se rendre dans l'habitacle, et un diffuseur de parfum intégré communiquant avec le conduit par l'intermédiaire d'ouvertures ménagées dans la paroi du corps creux.FR-A-2 821 022 describes an aerator for perfuming the air introduced into the passenger compartment of a vehicle, this aerator comprising a hollow body delimiting a duct in which the air circulates to reach the passenger compartment, and an integrated perfume diffuser communicating with the conduit through openings in the wall of the hollow body.

L'air circulant dans le conduit ne peut toutefois pas venir au contact de la source de parfum située à l'intérieur du diffuseur de parfum du fait que sa direction d'écoulement est parallèle à la sortie des ouvertures reliant le conduit au diffuseur de parfum.The air circulating in the duct, however, can not come into contact with the perfume source located inside the perfume diffuser because its flow direction is parallel to the outlet of the openings connecting the duct to the perfume diffuser .

La quantité de parfum diffusée est toutefois très faible, ce qui ne permet pas de parfumer de façon rapide et efficace l'habitacle du véhicule.The amount of perfume diffused is however very low, which does not allow to perfume quickly and efficiently the passenger compartment of the vehicle.

PATENT ABSTRACTS OF JAPAN vol. 013, n° 013 (M-783) et JP 63 222919 A décrivent un diffuseur de parfum comportant un boîtier dans lequel une plaquette aromatique est insérable et qui est destiné à être introduit dans un évidemment ménagé dans la face antérieure d'un aérateur d'automobile.PATENT ABSTRACTS OF JAPAN vol. 013, No. 013 (M-783) and JP 63 222919 A disclose a perfume diffuser having a housing in which an aromatic plate is insertable and which is intended to be introduced into a recess in the front face of an aerator d automobile.

Ce diffuseur de parfum a toutefois l'inconvénient, une fois en place dans l'aérateur, de réduire la section de passage de l'écoulement d'air vers l'habitacle de l'automobile, et par conséquent la qualité de l'aération à l'intérieur de l'habitacle.However, this perfume diffuser has the disadvantage, once in place in the aerator, reducing the passage section of the air flow to the passenger compartment of the automobile, and therefore the quality of the aeration inside the cockpit.

La présente invention se propose de remédier aux inconvénients des aérateurs décrits dans les documents susvisés et, pour ce faire, elle a pour objet un aérateur ayant la structure indiquée au premier paragraphe ci-dessus et caractérisé en ce que le diffuseur de parfum comporte une dérivation dans laquelle est disposée la source de parfum, cette dérivation étant située à l'intérieur du corps creux et destinée à être empruntée par au moins une partie de l'air circulant de l'orifice d'entrée à l'orifice de sortie.The present invention proposes to overcome the drawbacks of the aerators described in the aforementioned documents and, for this purpose, it relates to an aerator having the structure indicated in the first paragraph above and characterized in that the perfume diffuser comprises a bypass in which the perfume source is disposed, this bypass being located inside the hollow body and intended to be taken by at least a portion of the air flowing from the inlet orifice to the outlet orifice.

Comme le diffuseur de parfum est intégré au corps creux de l'aérateur, l'utilisateur du véhicule n'a plus à faire preuve d'ingéniosité pour installer un diffuseur indépendant dans ce dernier.As the perfume diffuser is integrated into the hollow body of the aerator, the user of the vehicle no longer has to be ingenious to install an independent diffuser in the latter.

En outre, grâce à sa dérivation qui n'a pas d'équivalent dans les diffuseurs de l'état antérieur de la technique, le diffuseur selon l'invention permet au parfum de se mélanger intimement avec l'air introduit dans l'habitacle et de se répartir rapidement et uniformément dans ce dernier.In addition, thanks to its derivation which has no equivalent in the diffusers of the prior art, the diffuser according to the invention allows the perfume to mix intimately with the air introduced into the cabin and to spread quickly and evenly in the latter.

Selon un mode de réalisation préféré de l'invention, le diffuseur de parfum comprend un corps comportant un conduit qui constitue la dérivation et un logement qui communique avec le conduit et est conformé pour recevoir une cartouche de parfum, un élément de réglage déplaçable par rapport au corps entre une première position extrême dans laquelle il permet au logement de communiquer librement avec le conduit et une deuxième position extrême dans laquelle il isole totalement le logement du conduit, et des moyens de commande pour déplacer l'élément de réglage entre ses positions extrêmes et contrôler ainsi la diffusion du parfum dans l'air introduit dans l'habitacle.According to a preferred embodiment of the invention, the perfume diffuser comprises a body comprising a duct which constitutes the bypass and a housing which communicates with the duct and is shaped to receive a perfume cartridge, a control element movable relative to to the body between a first end position in which it allows the housing to freely communicate with the conduit and a second end position in which it completely isolates the housing of the conduit, and control means for moving the adjustment element between its extreme positions and thus control the diffusion of the perfume into the air introduced into the cabin.

Ce diffuseur a une structure à la fois compacte et simple et sa présence dans l'aérateur ne modifie pratiquement pas le prix de revient de ce dernier.This diffuser has a structure both compact and simple and its presence in the aerator does not substantially change the cost price of the latter.

Avantageusement, l'élément de réglage comprend un obturateur déplaçable dans le logement entre une position extrême active dans laquelle il obture complètement le conduit et une position extrême inactive dans laquelle il est en totalité hors du conduit.Advantageously, the adjusting element comprises a shutter movable in the housing between an active end position in which it completely closes the conduit and an inactive extreme position in which it is completely out of the conduit.

Grâce à cet obturateur, l'émission de parfum dans l'habitacle du véhicule peut donc être contrôlée très facilement par le conducteur ou toute autre personne accompagnant celui-ci.Thanks to this shutter, the emission of perfume in the passenger compartment of the vehicle can therefore be controlled very easily by the driver or any other person accompanying it.

De préférence, le logement comprend deux parties situées de part et d'autre du conduit.Preferably, the housing comprises two parts located on either side of the duct.

L'obturateur peut dans ce cas être reçu dans l'une des deux parties du logement et se présenter sous la forme d'un étui comportant un fond à son extrémité la plus éloignée du conduit.The shutter can in this case be received in one of the two parts of the housing and be in the form of a case having a bottom at its end farthest from the conduit.

Par ailleurs, le dispositif de réglage est de préférence déplaçable en translation sur le corps, ce mode de déplacement nécessitant des moyens simples et faciles à mettre en place.Moreover, the adjustment device is preferably displaceable in translation on the body, this mode of displacement requiring simple means and easy to implement.

Selon une caractéristique particulière de l'invention, des moyens d'immobilisation sont prévus pour retenir l'élément de réglage dans ses deux positions extrêmes.According to a particular characteristic of the invention, immobilization means are provided for retaining the adjusting element in its two extreme positions.

Le conducteur ou un passager du véhicule peut donc ainsi immobiliser le dispositif de réglage dans l'une ou l'autre de ses positions extrêmes lorsqu'il souhaite que la quantité de parfum diffusée dans l'habitacle du véhicule soit maximale ou au contraire nulle.The driver or a passenger of the vehicle can thus immobilize the adjustment device in one or other of its extreme positions when it wishes that the amount of perfume diffused in the passenger compartment of the vehicle is maximum or otherwise zero.

Selon un mode de réalisation préféré, les moyens d'immobilisation comprennent des organes complémentaires situés respectivement sur le corps et sur l'élément de réglage, ces organes étant constitués respectivement par une lame élastique comportant une dépression transversale et par deux saillies espacées, la dépression et l'une des saillies coopérant entre elles lorsque l'élément de réglage est dans la position extrême correspondante.According to a preferred embodiment, the immobilizing means comprise complementary members located respectively on the body and on the adjusting element, these members being constituted respectively by an elastic blade having a transverse depression and by two spaced projections, the depression and one of the projections cooperating with each other when the adjusting member is in the corresponding end position.

Grâce à ces moyens d'immobilisation, la quantité de parfum diffusée peut être modifiée de façon continue lorsque l'élément de réglage est déplacé de l'une à l'autre de ses positions extrêmes.Thanks to these immobilization means, the amount of diffused perfume can be changed continuously when the adjustment element is moved from one to the other of its extreme positions.

Selon une autre caractéristique particulière de l'invention, les moyens de commande comprennent une molette d'actionnement adjacente à l'orifice de sortie, cette molette étant montée rotative sur le corps creux et reliée à l'élément de réglage par une articulation autorisant un déplacement en translation de celui-ci.According to another particular characteristic of the invention, the control means comprise an actuating wheel adjacent to the outlet orifice, this wheel being rotatably mounted on the hollow body and connected to the adjustment element by an articulation allowing a translational displacement thereof.

Ces moyens de commande ont l'avantage d'être simples et faciles à actionner.These control means have the advantage of being simple and easy to operate.

Dans le mode de réalisation présenté ci-dessus, la cartouche de parfum est retenue au moins partiellement dans le logement du diffuseur et comporte une partie évidée au niveau du conduit.In the embodiment presented above, the perfume cartridge is retained at least partially in the diffuser housing and has a recessed portion at the conduit.

Etant donné que la partie évidée de la cartouche de parfum est située au niveau du conduit, le parfum peut être facilement entraîné par l'air circulant dans le conduit.Since the recessed portion of the perfume cartridge is located at the conduit, the perfume can be easily entrained by the air flowing in the conduit.

Par ailleurs, le corps creux de l'aérateur a de préférence une section transversale rectangulaire, tandis que le diffuseur de parfum est de préférence adjacent à l'un des côtés transversaux du corps creux.On the other hand, the hollow body of the aerator preferably has a rectangular cross-section, while the perfume diffuser is preferably adjacent to one of the transverse sides of the hollow body.

Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple nullement limitatif en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective schématique et partielle d'un aérateur conforme à l'invention ;
  • la figure 2 est une vue éclatée de l'aérateur visible sur la figure 1, les déflecteurs situés au niveau de l'orifice de sortie n'étant pas représentés ;
  • la figure 3 est une vue en coupe schématique selon la ligne III-III de la figure 1, l'élément de réglage du diffuseur de parfum étant représenté dans sa position extrême dans laquelle il empêche la diffusion du parfum ; et
  • la figure 4 est une vue analogue à la figure 3 mais montre l'élément de réglage dans son autre position extrême dans laquelle il permet une diffusion libre du parfum.
An embodiment of the present invention will be described hereinafter by way of non-limiting example with reference to the accompanying drawings in which:
  • Figure 1 is a schematic and partial perspective view of an aerator according to the invention;
  • Figure 2 is an exploded view of the aerator visible in Figure 1, the baffles located at the outlet orifice not being shown;
  • Figure 3 is a schematic sectional view along the line III-III of Figure 1, the adjusting element of the perfume diffuser being shown in its extreme position in which it prevents the diffusion of perfume; and
  • Figure 4 is a view similar to Figure 3 but shows the adjustment element in its other extreme position in which it allows free diffusion of the perfume.

L'aérateur représenté sur les dessins a été conçu pour introduire de l'air parfumé dans l'habitacle d'un véhicule, notamment d'une automobile.The aerator shown in the drawings has been designed to introduce scented air into the passenger compartment of a vehicle, including an automobile.

Il va de soi cependant que l'on ne sortirait pas du cadre de la présente invention si cet aérateur était utilisé pour introduire de l'air parfumé dans d'autres moyens de transport, par exemple dans un wagon ou un avion, ainsi que dans des immeubles d'habitation ou de bureaux pourvus d'un système de conditionnement d'air.It goes without saying, however, that it would not be outside the scope of the present invention if this aerator was used to introduce perfumed air into other means of transport, for example in a wagon or an airplane, as well as in residential or office buildings with an air conditioning system.

L'aérateur visible sur les dessins comprend tout d'abord un corps creux 1 pourvu à l'une de ses extrémités d'un orifice d'entrée 2 relié d'une manière connue en soi à la source d'air conditionné du véhicule et à son autre extrémité d'un orifice de sortie 3 débouchant dans l'habitacle.The aerator visible in the drawings first comprises a hollow body 1 provided at one of its ends with an inlet orifice 2 connected in a manner known per se to the air conditioning source of the vehicle and at its other end an outlet opening 3 opening into the passenger compartment.

Le corps creux 1 comporte des déflecteurs 4 destinés à modifier l'orientation du flux d'air émis dans l'habitacle, ces déflecteurs, non représentés sur la figure 2, étant montés pivotants dans le corps 1 et ayant l'un de leurs côtés longitudinaux pratiquement au niveau de l'orifice de sortie 3.The hollow body 1 comprises deflectors 4 intended to modify the orientation of the air flow emitted into the passenger compartment, these deflectors, not shown in Figure 2, being pivotally mounted in the body 1 and having one of their sides longitudinals substantially at the outlet port 3.

Une plaque 5 fixée sur le tableau de bord du véhicule est pourvue d'un trou 6 dans le lequel s'étend l'extrémité du corps 1 comportant l'orifice de sortie 3 et sert de cache aux autres parties du corps 1.A plate 5 fixed to the dashboard of the vehicle is provided with a hole 6 in which extends the end of the body 1 having the outlet orifice 3 and serves as a cover for the other parts of the body 1.

L'aérateur comprend également un diffuseur de parfum 7 intégré au corps 1 et pourvu d'une dérivation 8 destinée à être empruntée par une partie de l'air circulant de l'orifice d'entrée 2 à l'orifice de sortie 3.The aerator also comprises a perfume diffuser 7 integrated in the body 1 and provided with a bypass 8 intended to be borrowed by a part of the air flowing from the inlet orifice 2 to the outlet orifice 3.

Le diffuseur de parfum 7, qui est particulièrement bien visible sur la figure 2, comprend un corps 9 comportant un conduit constitué par la dérivation 8 et un logement 10 comprenant deux parties 10a, 10b situées de part et d'autre du conduit 8, ces deux parties étant dans le prolongement l'une de l'autre et communiquant avec le conduit 8 au niveau de leurs extrémités qui sont les plus proches.The perfume diffuser 7, which is particularly clearly visible in FIG. 2, comprises a body 9 comprising a conduit constituted by the bypass 8 and a housing 10 comprising two parts 10a, 10b located on either side of the conduit 8, these two parts being in the extension of one another and communicating with the conduit 8 at their ends which are the closest.

Le diffuseur de parfum comprend également un élément de réglage 11 déplaçable par rapport au corps 9 entre une première position extrême visible sur la figure 4 dans laquelle il permet au logement 10 de communiquer librement avec le conduit 8 et une deuxième position extrême visible sur la figure 3 dans laquelle il isole totalement le logement 10 du conduit 8.The perfume diffuser also comprises an adjustment element 11 displaceable relative to the body 9 between a first extreme position visible in FIG. 4 in which it allows the housing 10 to freely communicate with the conduit 8 and a second extreme position visible in Figure 3 in which it completely isolates the housing 10 of the conduit 8.

L'élément de réglage 11 comprend un obturateur 12 s'avançant dans la partie 10a du logement 10, du côté opposé à la partie 10b de celui-ci, et déplaçable en translation dans celui-ci entre une position extrême active visible sur la figure 3 et dans laquelle il obture complètement le conduit 8 et une position extrême inactive visible sur la figure 4 et dans laquelle il est en totalité hors du conduit 8.The adjusting element 11 comprises a shutter 12 extending in the portion 10a of the housing 10, on the side opposite to the portion 10b thereof, and movable in translation thereon between an active end position visible in the figure 3 and in which it completely closes the duct 8 and an inactive extreme position visible in FIG. 4 and in which it is entirely out of the duct 8.

Comme on peut le voir sur les figures 3 et 4, l'obturateur 12 se présente sous la forme d'un étui comportant un fond 13 à son extrémité la plus éloignée du conduit.As can be seen in Figures 3 and 4, the shutter 12 is in the form of a case having a bottom 13 at its end farthest from the duct.

L'élément de réglage 11 comprend également un manchon 14 s'étendant parallèlement à l'obturateur 12. Le manchon 14 est enfilé sur une tige 15 prévue sur le corps 9 et s'étendant parallèlement au logement 10The adjusting element 11 also comprises a sleeve 14 extending parallel to the shutter 12. The sleeve 14 is threaded onto a rod 15 provided on the body 9 and extending parallel to the housing 10

Grâce à cette tige, l'élément de réglage 11 peut être déplacé en translation par rapport au corps 9 tout en restant parallèle au logement 10.With this rod, the adjustment element 11 can be displaced in translation relative to the body 9 while remaining parallel to the housing 10.

On notera ici que pour éviter que l'élément de réglage 11 puisse tourner sur le corps 9, celui-ci comporte une nervure longitudinale 16 s'étendant parallèlement au logement 10 et reçue dans une rainure de forme correspondante ménagée dans l'élément de réglage, cette rainure n'étant pas visible sur les dessinsIt should be noted here that, in order to prevent the adjusting element 11 from rotating on the body 9, the latter comprises a longitudinal rib 16 extending parallel to the housing 10 and received in a groove of corresponding shape formed in the adjusting element , this groove not being visible on the drawings

Le logement 10 du corps 9 est prévu pour recevoir une cartouche de parfum 17 à l'intérieur de laquelle est disposé un support non représenté portant le parfum et à partir duquel celui-ci peut être diffusé de manière contrôlée.The housing 10 of the body 9 is provided to receive a perfume cartridge 17 inside which is disposed a not shown support carrying the perfume and from which it can be diffused in a controlled manner.

La cartouche 17 comporte une partie évidée 18 au voisinage de son extrémité inférieure, la partie évidée 18 se trouvant au niveau du conduit 8 lorsque la cartouche 17 est en place dans le logement 10, comme cela ressort des figures 3 et 4.The cartridge 17 has a recessed portion 18 near its lower end, the recessed portion 18 being at the level of the duct 8 when the cartridge 17 is in place in the housing 10, as is apparent from Figures 3 and 4.

Lorsque l'obturateur 12 est dans sa position extrême active représentée sur la figure 3, il constitue une barrière entre la cartouche 17 et le conduit 8 et s'oppose à une diffusion de parfum en empêchant l'air de circuler dans ce dernier.When the shutter 12 is in its extreme active position shown in Figure 3, it forms a barrier between the cartridge 17 and the conduit 8 and opposes a perfume diffusion by preventing air from circulating in the latter.

En revanche, lorsqu'il est dans sa position extrême inactive représentée sur la figure 4, il ne se trouve pas à l'intérieur du conduit 8 de sorte que de l'air peut circuler dans celui-ci et entraîner avec lui le parfum diffusé par la cartouche.On the other hand, when it is in its inactive extreme position shown in FIG. 4, it is not inside the duct 8 so that air can circulate in it and carry with it the diffused perfume. by the cartridge.

Grâce au fond 13 de l'obturateur 12, les fuites d'air au niveau de l'extrémité inférieure de la partie 10a du logement 10 sont bien entendu évitées.Thanks to the bottom 13 of the shutter 12, air leakage at the lower end of the portion 10a of the housing 10 are of course avoided.

Le diffuseur de parfum comprend par ailleurs des moyens de commande 19 à l'aide desquels l'élément de réglage 11 peut être déplacé entre ses positions extrêmes afin de contrôler la diffusion du parfum dans l'air introduit dans l'habitacle du véhicule.The perfume diffuser further comprises control means 19 by means of which the adjustment element 11 can be moved between its extreme positions in order to control the diffusion of the perfume into the air introduced into the passenger compartment of the vehicle.

Dans le mode de réalisation représenté, les moyens de commande 19 comprennent une molette d'actionnement 20 faisant légèrement saillie dans un orifice 21 ménagé dans la plaque 5 et ayant des dimensions appropriées.In the embodiment shown, the control means 19 comprise an actuating wheel 20 projecting slightly into an orifice 21 formed in the plate 5 and having appropriate dimensions.

La molette 20 est montée rotative sur un axe cylindrique 21 (visible sur la figure 2) du corps creux 1 et comporte une protubérance 22 portant deux tétons coaxiaux 23 sur ses faces, ces tétons étant reçus dans des trous oblongs 24 ménagés dans les ailes 25 d'une chape prévue sur l'élément de réglage 11.The wheel 20 is rotatably mounted on a cylindrical axis 21 (visible in Figure 2) of the hollow body 1 and has a protrusion 22 carrying two coaxial studs 23 on its faces, these pins being received in oblong holes 24 formed in the wings 25 a clevis provided on the adjusting element 11.

On conçoit aisément que grâce à ce montage particulier, il suffit de faire tourner manuellement la molette 20 dans un sens ou dans l'autre pour amener l'obturateur dans l'une ou l'autre de ses positions extrêmes.It is easy to see that, thanks to this particular arrangement, it suffices to manually turn the wheel 20 in one direction or the other to bring the shutter into one or the other of its extreme positions.

L'aérateur qui vient d'être décrit comprend par ailleurs des moyens 26 pour immobiliser l'élément de réglage 11 dans ses deux positions extrêmes.The aerator which has just been described further comprises means 26 for immobilizing the adjusting element 11 in its two extreme positions.

Dans le mode de réalisation représenté, les moyens d'immobilisation 26 comprennent deux saillies 27 prévues sur l'élément de réglage 11 et séparées l'une de l'autre par une distance égale à celle que doit parcourir ce dernier pour passer de l'une à l'autre de ses deux positions extrêmes.In the embodiment shown, the immobilizing means 26 comprise two projections 27 provided on the adjusting element 11 and separated from each other by a distance equal to that which must traverse the latter to pass from the one to the other of its two extreme positions.

Ils comprennent également une lame élastique 28 fixée sur le corps 9 du diffuseur de parfum et comportant dans sa partie médiane une dépression transversale 29 destinée à venir coopérer avec les saillies 27 lorsque l'élément de réglage 11 est amené dans ses positions extrêmes.They also comprise an elastic blade 28 fixed on the body 9 of the perfume diffuser and having in its middle part a transverse depression 29 intended to cooperate with the projections 27 when the adjustment element 11 is brought to its extreme positions.

Etant donné que la dépression 29 a une forme complémentaire de celle des saillies 27, l'élément de réglage 11 peut être immobilisé relativement fermement dans ses positions extrêmes de sorte qu'il est nécessaire d'exercer un certain effort sur la molette 20 pour l'éloigner de ses positions extrêmes.Since the depression 29 has a shape complementary to that of the protrusions 27, the adjusting element 11 can be relatively firmly immobilized in its extreme positions so that it is necessary to exert a certain force on the wheel 20 for 'move away from its extreme positions.

La résistance, opposée est voulue afin d'éviter que l'élément de réglage se déplace de façon intempestive, par exemple sous l'effet de vibrations.The opposite resistance is intended to prevent the adjustment element from moving unexpectedly, for example under the effect of vibrations.

Bien entendu, l'élément de réglage peut être immobilisé dans une position intermédiaire quelconque entre ses positions extrêmes par suite d'une rotation prédéterminée de la molette 20, ce qui permet d'ajuster la quantité de parfum diffusée dans le réceptacle du véhicule.Of course, the adjustment element can be immobilized in any intermediate position between its extreme positions as a result of a predetermined rotation of the wheel 20, which adjusts the amount of perfume diffused into the receptacle of the vehicle.

Dans le mode de réalisation décrit ci-dessus, les deux saillies 27 sont prévues sur l'élément de réglage 11 tandis que la lame élastique 28 est fixée sur le corps 9.In the embodiment described above, the two projections 27 are provided on the adjustment element 11 while the elastic blade 28 is fixed on the body 9.

Il va de soi que les deux saillies 27 pourraient être portées par le corps 9 et la lame élastique 28 par l'élément de réglage 11.It goes without saying that the two projections 27 could be carried by the body 9 and the elastic blade 28 by the adjustment element 11.

Pour être complet, on indiquera que les orifices d'entrée 2 et de sortie 3 du corps creux 1 de l'aérateur représenté sur les dessins ont une forme globalement rectangulaire, mais rien ne s'oppose à ce qu'ils aient une toute autre forme.To be complete, it will be pointed out that the inlet and outlet orifices 3 of the hollow body 1 of the aerator shown in the drawings have a generally rectangular shape, but there is nothing to prevent them from having a completely different shape. form.

Par ailleurs, le diffuseur de parfum 7 est adjacent à l'un des côtés transversaux du corps creux, mais il pourrait être prévu en un tout autre endroit sur le corps creux 1.On the other hand, the perfume diffuser 7 is adjacent to one of the transverse sides of the hollow body, but it could be provided in a completely different place on the hollow body 1.

Enfin, on notera que la cartouche de parfum 17 est de conception classique. Elle peut être mise en place très facilement puisque la plaque 5 comporte un orifice permettant son introduction directe dans le logement 10 du corps 9 du diffuseur de parfum 7.Finally, it will be noted that the perfume cartridge 17 is of conventional design. It can be set up very easily since the plate 5 has an orifice allowing its direct introduction into the housing 10 of the body 9 of the perfume diffuser 7.

Il ressort de ce qui précède que l'aérateur et le diffuseur de parfum qui viennent d'être décrits constituent un élément unique grâce auquel le conducteur ou un passager d'un véhicule peut commander très facilement la diffusion d'un parfum dans l'habitacle puisque ce parfum, lorsque sa diffusion est souhaitée, est introduit directement dans l'air sortant de l'aérateur.It follows from the foregoing that the aerator and the diffuser of perfume which have just been described constitute a single element by which the driver or a passenger of a vehicle can very easily control the diffusion of a perfume in the passenger compartment. since this perfume, when its diffusion is desired, is introduced directly into the air coming out of the aerator.
